Would anyone care if I lit up the end? It would remove the snow, but it'd also remove all enderman spawns (at least in the traveled areas). During this process, I'll also add a better road and maybe a portal house.

The reason I ask is that there's a sign telling people not to add torches, but it seems to indicate that the snow is in place to reduce spawns (torches remove spawns).

So the issue isn't actually spawns, but teleportable locations. The endermen spawn elsewhere, then they teleport to the lit up cells, and because the enderman farm is within 128 blocks, they don't despawn.

Are you sure? While building it, I could have sworn I made it more than 128 blocks...

Also, how does snow deal with the teleportation? Seems like torches would prevent spawning in the area entirely, which would be better than just reducing them (and removing teleportation).
